Here's what they say about us

Select a category:
We used GSA for an event we had in London. They handled lead generation and telemarketing for the event. They were very thorough and touched base with us every step of the way to make sure the campaign was successful. They are professional and prompt and kept us up to date with the campaign and the milestones as we progressed closer to the event. I highly recommend if you need a telemarketing & B2B lead generation services you should reach out to GSA and talk to Jonathan and Monica
Boost Media International

I highly recommend the GSA team. The service they delivered was extremely responsive to all our requirements, and effective in getting Waisl in front of our senior decision-makers in hard-to-reach target airports.

For our European airport expansion, GSA executed a multi-channel exercise across phone, email, and LinkedIn, resulting in a robust database of core targets, within 21 key airports. The team successfully reached a significant number of Decision Making Contacts and delivered a professional, consistent approach that led to important discussions and engagement for our business development.

Their efforts led to concrete outcomes, securing high-level engagement at major hubs. GSA’s strategic and operational support was invaluable in helping WAISL navigate the complex, multi-front engagement required in the airport sector.

We would recommend them to any organisation with the objective to develop its B2B business.


Waisl
We engaged GSA to support our event delegate telemarketing campaign, and the results were excellent. Their team was professional, responsive and highly organised — they quickly understood our goals and delivered quality leads that helped boost delegate registration. Communication throughout the process was clear and efficient. We’re very pleased with the service and would happily work with them again.
The Surgery Show

We partnered with this agency and the experience was excellent. The team was highly professional, proactive, and attentive to our needs. They managed telemarketing effectively, ensuring clear communication and tangible results. A special mention goes to their Italian telemarketer, whose exceptional communication skills and ability to engage with our audience made a real difference. Highly recommended for anyone looking for a reliable, performance-driven partner.

Ansell
Having collaborated with Jonathan and his superb team for the last 13 years, I can easily say that they are consummate professionals and we look forward to working with them for many more years.
Peter Radcliffe, Founder
Exceptional service and can’t rate them high enough. Reporting is also exceptional!
Orthene

We partnered with GSA to support our sales efforts, and they exceeded our expectations. Kevin and the rest of the team were incredibly reliable and provided tremendous support throughout the campaign. They generated a significant number of highly qualified leads, which not only boosted our sales but also helped propel our business forward. Their reporting was impeccable, and we found their analytics incredibly useful in understanding campaign performance and refining our strategies. The campaign was a huge success, and we were thoroughly impressed with their professionalism and dedication. We would not hesitate to work with GSA again in the future

Halo
GSA’s telemarketing campaign carried out on our behalf produced a wealth of helpful information. Jonathan and Kevin provide a professional and friendly service, and their team of telemarketers must be among the best in class.
Motor Fuel Group

GSA demonstrated exceptional responsiveness to our evolving project demands and organisational needs. Julia adeptly understood our ideas and concepts and effectively captivated prospective leads with her exceptional telephone etiquette and strong communication skills.

The feedback and reporting provided by Kevin and Julia were incredibly insightful, enabling us to explore alternative avenues and make informed strategic choices.

I cannot speak highly enough of GSA for their blend of professionalism and personal touch in their engagement with our company. I wholeheartedly endorse their services.

Graco
A great positive approach to telemarketing, very open communication, and good results
Meon
Targeted approach and clear results. I cannot recommend the GSA team enough!
Miele Professional

We engaged GSA Marketing to do telemarketing/LinkedIn/Email campaigns for our company. We had a difficult and specific target audience, and GSA worked diligently over a few months to reach these people, and then deliver these campaigns efficiently and effectively. As a result of these campaigns we are now in communications with many of our most desired target leads, well down the long sales cycle that our business necessitates.

I would highly recommend GSA to everyone, I have really enjoyed working with Jonathan, Kevin and Alex. We will be carrying out more campaigns in the new year.

Enviro Waste Management

It was a joy working with the team from GSA. The ability to conduct weekly reviews directly with the telemarketers was very reassuring and allowed us to tweak our messages in a timely manner. We are very satisfied not only with the results, but the process and delivery as well.

ITMA Services

We partnered with GSA so we could quickly, professionally, and effectively reach-out to our European customers. GSA enabled us to interact with our client base at a speed with which we would never have been able to replicate using just our in-house language team. We had regular, professional updates with the project team and had thorough and insightful quantitative data, as well as interesting qualitative feedback. It was an enjoyable and successful collaboration.

International Dance Supplies Ltd

We have worked with GSA for more than 10 years.  Throughout that time they have been simply outstanding.
From a campaign perspective, Kevin and Julia are quite the dream team – Julia’s ability to get to speak to the right individual and put across a compelling message is simply second to none & Kevin’s superb management of the campaign ensures you are fully updated at the click of a button.

Jonathan’s ability to transform our initial email/linked in wording into something that was both meaningful and concise ensured we had a superb hit rate.


We really can’t thank them enough and are already in discussions about our next campaign

Competent Adviser
We have known Jonathan and his team at GSA for many years. Having used them on multiple B2B campaigns I can certainty recommend them to any company needing an effective telemarketing company that is focused on results. GSA’s telemarketers have vast experience and the effort they go to understand the product and service is brilliant and shows in the results. Keep up the great work!
Adkwik

GSA has supported my team over a number of years to deliver high quality leads to our sales teams. Their professional approach from the initial brief through to calling and reporting, fully integrates into our lead generation campaigns.

Veolia

We worked with GSA on a B2B marketing campaign following sub-par results using in-house resources. We initially decided on a set number of hours but ended up doubling it after our conversion rate was increased by an amazing 108%. GSA ensured our campaign results were updated on a daily basis and their team followed up with us weekly to ensure the campaign was going as planned. We were impressed with the team’s professional, yet warm manner, making them an absolute pleasure to work with. We look forward to working with GSA in the future.

Nuclei Group 

The GSA team have been supporting some of our Marketing outreach efforts and we could not be more satisfied with the service. They are great at giving advice, professional in executing campaigns, and efficient in driving results. A real pleasure to work with them

 

Oxentia Ltd

The team at GSA were extremely helpful and professional, providing advice and thorough explanations on each part of the project we worked with them on. They took the time to meet with us face to face, to discuss the best way to approach the work, and were available to speak to whenever needed. Jonathan is a fountain of knowledge and went above and beyond to help us with any questions we had. It wasn’t the easiest project to work on but GSA helped every step of the way. Thank you!

U+I Global PLC

We were extremely pleased with the activity since we had a large unqualified database that meant our internal team were unable to identify and focus on the best targets for new business development. With the help of GSA, we were able to reach out to prime prospects much more quickly for higher value sales. We would recommend GSA for anyone that wants to generate targeted leads for their business.

FÖRST GmbH

Fully recommended Jonathan & Kevin and the rest of the GSA team and the service they offer. Very easy to work with and delivered real results for our business despite the campaign being seriously impacted by CV19!

HTS Spares

Right from the start GSA understood the needs of our cross-Europe tele-research campaign fully & were able to advise and adapt to our specific requirements. The daily reporting helped us understand, first-hand, how the campaign was progressing and help keep costs within the allocated budgets. They were very flexible in terms of the native speakers used as subsequent data was added to the project. I would highly recommend them and will certainly be using them for other projects”

OKI Europe Ltd

The Sales team at Ultrimax were impressed with the professional assistance of GSA Business Development, clear visual reporting on a daily basis ensured focused efforts on generating well profiled leads, which helped bolster our ongoing sales growth in 2019. I would recommend GSA Business Development to anyone looking for that extra support in lead generation

Ultrimax

GSA are a company with a difference, adding value above what is expected when it comes to telephone campaigns. To be specific about that, we got advice and data cleansing as extras. They are willing to link in with systems and have outstanding reporting. But more than all of that they are transparent so that you know exactly where you stand on a campaign. We would recommend them.

Plus Packaging

GSA allowed us to explore a new vertical and gave us valuable insight into this new market.

They delivered on the campaign goals and we were really impressed with the quality of the calls.

 

Wexer

“GSA took on board our comprehensive brief and provided an excellent service from campaign inception through to analysis upon completion. We were particularly impressed by the professionalism and telephone manner of Julia March in conducting the calls to medical staff. Julia was quick to understand our technology and the correct terminology to use, with her distinct conversational tone helping to sell the benefits and uses of our speech privacy systems rather than focusing on the product. Likewise, the communications from both Julia and Kevin Harmsworth throughout ensured we remained fully up to date with progress, even when the campaign was temporarily put on hold to garner better results later in the year.”

Vaughan Sound Installations Ltd

“GSA Marketing worked with us on a test campaign to assess the viability of an outbound sales function in what is a relatively niche sector (outdoor learning residential breaks for Special Educational Needs schools) for our centre in the Lake District. The target market was Teachers or Special Needs Coordinators within schools and colleges, with us providing contact details, albeit un-validated, from our existing database – a combination of organisations who had enquired but never visited, or lapsed. We asked them to pitch for our business from a shortlist of potential suppliers and we chose them due to the bespoke attention they paid to our enquiry, and once selected were very pleased with the personal attention they gave us at a senior level. Setting up the campaign with them was very straightforward and we were impressed by the level of reporting through the campaign and the quality of the calls made by their staff, with each call being recorded. Warm leads were passed to us to follow-up and the quality of the contact information supplied very good. The nature of our business is that 1st contact to booking is usually relatively long, but we were delighted that the month long campaign quickly resulted in a booking from an entirely new customer which more than covered the capital cost of the test. We also now have several schools visiting the centre on an inspection trip, and previous experience tells us that a proportion of these will also convert. All in all, we were very pleased with this outbound sales test and GSA’s contribution to its success. We now have the confidence to invest in sales resource at the centre as a direct result”

Lake District Calvert Trust

GSA Business Development, was contracted by the Hong Kong Trade Development Council from November 2017 to May 2018 to provide telemarketing services for our GDPR consent campaign in the markets covered by this office.

GSA called a total of 74,000 records and managed to secure a good consent rate. The company was responsive and always willing to listen to our fears and concerns. GSA is a cool-minded and professional TM agency, and I was happy with the results that they obtained.

GSA was awarded the contract on the basis of a competitive tender, and so their costs were reasonable. Thanks to their efforts, we managed to cover our databank before the deadline of 25 May.

I would happily appoint them again. All things being equal.

Hong Kong Trade and Development Council (HKTDC)

We found GSA very professional and helpful when organising our telemarketing campaign, we worked together during the planning and the results were better than expected. We have used them again in a second campaign which also offered good results. The telesales team, was professional and friendly.

FPS Air Compressors Ltd

We decided to use GSA Business Development Ltd to support us with our Christmas Marketing Campaigns. Christmas is an important time of year for us as many organisations use this festive period to award their staff with Love2shop Vouchers and Cards for Christmas Bonuses and Annual Awards. Here at Love2shop Business Services, our peak season begins in October and runs until a few days before Christmas. As a result, the volume of inbound calls meant that we were unable to focus on outbound calling as much as we would have liked to. In the past, we have traditionally used our own resources for outbound calls as we like to stay on brand and ensure our customers receive the best experience possible. However due to the sheer volume of calls which needed to be made, we decided to pitch the business out to a few specialist agencies. From our initial meeting, I knew that GSA were the agency to use as they were smaller and more dynamic than the other agencies we’d spoken to, and in turn, I knew that we’d receive a better, more personal service. We were not disappointed, using a segmented approach, GSA contacted many of our customers and prospects at various stages of the their customer life cycle and generated a great number of quality hot leads for our Business Development Team to follow up. The success from this campaign was not achieved by luck. Processes such as the initial face to face briefing session, hot lead notifications, regular teleconferencing, recorded call listening, weekly reporting and the final post project review meant that we were in constant communication with GSA throughout the 8 week duration of the project. This communication was vital to ensure the calls remained relevant and compliant. As a result of this campaign, I would have no hesitation in recommending GSA Business Development Ltd for any telemarketing requirements.

Love2shop Brand Manager

“Some people believe that telemarketing is a luxury in a challenging economic environment. However I believe the opposite to be true, and getting out there and having quality prospect meetings is more important than ever. I haven’t found a better way to do this than via telemarketing and GSA is an exceptional example of a great telemarketing company. Taking a very consultative approach, they took their time to understand my business and proposition and then deliver quality appointments. I would highly recommend them.”

Coaching Company

“I would happily recommend the team at GSA Business Development. We appointed GSA for telemarketing services to support our business development strategy. I was very impressed with the levels of focus and energy that the GSA team brought to the project – this helped to quickly identify new commercial opportunities. GSA had limited experience in our sector but they very quickly got up to speed and were able to provide us with a number of excellent opportunities that have subsequently been converted into new clients.”

R.Bugg Fowarding Ltd

“I worked with GSA Marketing, for 2 very different telemarketing projects during the last year. One, for a campaign in UK, performed by British telemarketers to identify new sales opportunities performing in-depth investigational calls, and another, larger project, spread over 5 months, performed by a multi-language team, reaching 18 countries in Europe and North America with informative and scripted calls. In both projects, I’ve been very pleased with the service and the results provided, for several reasons, including helpful regular reporting and transparent communications, but mainly because the team at GSA adapted the service to our specifications. They have also always been a gold source of advice that I know I can rely on.”

Global chemical manufacturer

“The preparation that GSA put into our campaign was highly professional and set the foundations for an ongoing successful campaign. The initial meeting with Jonathan was so valuable in transferring information and assisting to embed GSA into our business. The questions he asked challenged my thinking about the offer we provide and how we differentiate ourselves. This is obviously crucial in converting prospects to Customers ….. once you have been able to secure a meeting with them of course !

Tyna has been absolutely marvellous in selling our initial offer to secure these meetings for me; with the right people. As far as our prospects are concerned Tyna is their first contact with our business. The quality of the information, all sent in a timely way; followed by weekly reports re iterates the professional company that GSA are.

As a result of the appointments that Tyna has set I have then been able to convert prospects to sales. We have already extended the contract to continue the success of working with GSA .”

Supplier to automotive sector

“We struggled to find a lead generation solution which would work for our organisation and tried a few options before finding GSA. The service which we experienced with them was far superior to anything else we’d found and some of the ideas put forward for our future marketing are really exciting. I’d definitely recommend anyone to give these guys a go.”

Valkyrie Support Services

“I have no hesitation is recommending the services of GSA.”

Digital Broadcast Dealers

“ABC look to be the ideal company that we are targeting. They were of ideal size and slap bang in the middle of the target industry. He seemed to be very aware of why I was visiting and they will hopefully be a future customer…..
If you can get me 100 more appointments just like this one, that would be absolutely perfect. Keep up the good work.

We engaged GSA Business Development in March 2011 to help us generate new business opportunities for our Social Media services. Initially, GSA undertook a strategic review of our offering and worked with us to define both the target audience and the proposition.

Having developed a targeted calling list, GSA senior level callers made telemarketing calls into blue chip organisations and have continuously made us high quality appointments with the types of companies we would wish to work with. Having also worked with GSA at my previous agency on several campaigns, I would highly recommend them if you need appointment setting and to generate new business opportunities with decision makers in blue chip organisations.

In the short time that we have been working with GSA, I have been delighted with the level of service that they have provided. We had a very difficult database to work with and GSA painstakingly went through it to ensure validity and helped us to design a telephone marketing strategy that has proved extremely effective.”

Worldwide Public Affairs & Strategic Communications

“GSA provided us with a flexible and professional sales and marketing service where we could utilize one or two consultants for as many hours a month as we wanted. Your staff are highly experienced and their subtle approach very much appealed to our target audience. They got us many appointments each month. I would have no hesitation in recommending you and your team to any company serious about expanding their business.”

Payroll Services Company

“We worked with GSA over two campaigns for more than a year and they provided us with high-quality telemarketing services. This has allowed us to keep a consistent flow of sales leads into blue-chip organisations from which we have generated new business. I would recommend GSA to any company looking to develop new business”

PR agency - London

“Expectations Exceeded! On the second day of our campaign we were simply delighted to get a call from Tonie telling us that she had secured two appointments for us with organisations that exactly matched our brief. Our initial view of GSA was that we were clearly dealing with experts in their field — this early on in our campaign our high expectations have already been exceeded and we are over the moon with how quickly Tonie has become an integral part of our team.”

Compliance company

“I thought our telemarketer was absolutely brilliant. I also thought the attention to detail was great, the focus on me (the client) was good and the reporting was excellent.”

Law Cost Specialists

“I just wanted to say a big thank you for arranging our appointment with Virgin Management last Tuesday, Our MD accompanied me to the meeting and he was very impressed that you had secured a meeting with the Chief Operating Officer no less!! We had an excellent meeting and will now present to the key people in two weeks. The spend is £1.5 to £2million.”

Travel Company

“Jonathan & his team at gsa, especially Laura, have provided us over the last few years with an extremely professional, cost-effective and successful route to prospective clients and we regard their work for us as an integral part of our success. I would have no hesitation in recommending them to other companies.”

Corporate Barter Company

“Just wanted to say thanks to Jonathan and the team for all of their efforts to put us infront of the people we need to do business with. Lead generation is always a challenge and GSA enabled us to increase the number of leads into our business. I was very pleased with the professional service and results and Carol is brilliant. I look forward to working with you again in the future”

DCS (London) Limited

“3 days of telemarketing to approx 50 publishers. I felt both Viv and Emmy provided an excellent service, were approachable, clear in their intentions and delivered an excellent service. The results of which were better than anticipated and I would not hesitate to use or recommend their services”
